* Reported price is value ÷ shares from the 13F as of period end — not a live market quote. Weight % is each long-equity position ÷ full 13F AUM, so rows may not sum to 100% when the filing includes options or other non-equity (excluded from this table). Share change and $ change are vs 2025 Q1. Click column headers to sort · click New / Hold / Add / Reduce to promote that move type to the top. Exit opens the last-held block below.
